Please allow up to 60 days to acclimate to your new mattress as it naturally adjusts to contour, comfort, and support you best. Premium memory foam is temperature-sensitive; it may feel firmer in cooler temperatures and softer in warmer ones. For your preferred comfort, please allow several hours for your memory foam mattress to adjust to the room’s temperature.
